Plastic extrusion cooling is a crucial step in the plastic manufacturing process. It involves rapidly cooling the extruded plastic material to ensure its dimensional stability and desired properties. One of the common solutions used for plastic extrusion cooling is an industrial process chiller.
An industrial process chiller is a refrigeration system specifically designed for cooling industrial processes. It consists of a compressor, condenser, evaporator, and an expansion valve. The chiller circulates a coolant (typically water or a water-glycol mixture) through the extrusion equipment to remove heat and maintain a consistent temperature.
An industrial process cooling system is used to remove heat from industrial processes or equipment to maintain optimal operating conditions. One type of industrial process cooling system is a central water cooling system. A central water cooling system, also known as a central chilled water system, is a common method for cooling various processes within a facility.
In a central water cooling system, chilled water is circulated through a network of pipes to different points of use where it absorbs heat from the processes or equipment. The heated water is then returned to a cooling source, typically a chiller, where it is cooled down before being recirculated.
A plastic processing chiller is a specific type of central water cooling system designed for cooling applications in the plastic processing industry. Plastic processing often involves heating the plastic material to a molten state and then shaping it into desired forms. This process generates significant amounts of heat that need to be removed to maintain the quality and efficiency of the plastic processing operation.
Plastic processing chillers are specifically engineered to provide precise and controlled cooling capabilities to meet the unique requirements of plastic processing equipment. They typically feature powerful compressors, heat exchangers, and a circulation pump to remove heat efficiently from the process.
The chiller unit in a plastic processing system cools the water by circulating it through the heat exchanger, which transfers heat from the water to a refrigerant. The refrigerant then goes through a compression and expansion process to remove heat and lower its temperature. The cooled refrigerant is then used to cool the water circulating through the system, and the process continues in a closed-loop fashion.
Overall, a plastic processing chiller, as part of an industrial process cooling system, plays a critical role in maintaining precise temperature control in plastic processing applications, ensuring product quality, and optimizing production efficiency.

An air cooled screw chiller is a type of refrigeration system used for cooling applications. It uses a screw compressor as the main component to circulate the refrigerant and remove heat from the system. Unlike water cooled chillers that require a separate cooling water source, air cooled screw chillers use ambient air as the cooling medium.
The application of air cooled screw chillers is wide-ranging and can be found in various industries and processes, including:
Commercial Buildings: Air cooled screw chillers are commonly used in office buildings, hotels, shopping malls, and other commercial facilities for air conditioning and HVAC (Heating, Ventilation, and Air Conditioning) applications.
Industrial Processes: They are utilized in industrial processes that require cooling, such as plastic manufacturing, rubber processing, metalworking, pharmaceutical production, food and beverage processing, and chemical manufacturing.
Data Centers: Air cooled screw chillers can provide cooling for data centers to maintain optimal temperatures for servers and sensitive electronic equipment.
Power Plants: They may be used for cooling in power generation plants, specifically for cooling turbine generator units and other equipment.
Hospitals: Air cooled screw chillers play a crucial role in providing cooling for critical areas in hospitals, such as operating rooms, laboratories, and medical equipment rooms.
Event Venues: They are frequently employed in convention centers, concert halls, and stadiums to maintain comfortable temperature conditions for large gatherings.
Air cooled screw chillers offer advantages such as simplified installation (no need for a separate cooling tower or water source), reduced water consumption, flexibility in installation locations, and ease of maintenance. However, they generally have slightly lower cooling capacity compared to water cooled chillers and may be affected by ambient temperature and air quality.
